ANSI 55-3 pin type porcelain insulators are specially designed for American market .
the product used for low voltage or medium voltage distributions lines.
normally those products will be with porcelain thread , lead head pins are recommended for use with those insulators . the cantilever strength test shall also be conducted with lead head pins .
because lead is soft , it will not hurt the porcelain thread .
the pin type insulator top can be normal type (with normal porcelain glaze ) or radio free type (with semi-conductive glaze) .
the insulator thread hole also covered with semi-conductive glaze .
we can provide lead head pins for insulator assembly , which can be suitable for wooden crossarm or steel cross arm .
Applications:
The 55-3 pin type porcelain insulator is used for low voltage or medium voltage distributions lines. These insulators are commonly installed vertically on metal or wooden structures based to support the
conductor .
Competitive Advantage:
The HIVOLT pin type insulator are made of high strength aluminum porcelain C-130 .
All units product are routine tested one by one , and sample tested by batches ,
so we guarantee all products are in high quality level .
we offer 3 years quality guarantee .
the product price are very competitive . if you have interests , please feel free contacting with us !
